PERFORMANCE NITRO BLACK

PERFORMANCE NITRO BLACK VALVES • 21-4N high strength stainless alloy • Swirl polished for improved flow characteristics • Fully undercut stem • Hard wafer tip • One piece forging • Proprietary liquid nitriding process that creates a valve that is smoother, stronger and more corrosion resistant than traditional chromed valves • Deep nitriding provides better ductility under the hard nitrided layer as proven in rotating-bending fatigue tests • Valve is less likely to break even if contacted by the piston • Greater surface hardness means less valve guide wear • Improved corrosion resistance even with exotic fuels • Our nitriding process is much cleaner than chroming- it’s better for the environment NITRO B L A C K NITRIDED HIGH PERFORMANCE VALVES ENGINE PRO’S Nitro Black racing valves are smoother than chrome.

Scanning electron microscope images back that up. Smoother valve stems mean less valve and valve guide friction. Less friction means more power, less wear and less chance of breakage. 4 NEW NUMBERS SHOWN IN BOLD FACE TYPE

NEW NITRO BLACK DIESEL PERFORMANCE VALVES For Ford Powerstroke, GM Duramax and Dodge Cummins Engines FEATURES • Exotic inconel alloy is designed to function in extreme heat and stress conditions • Stellite facing creates additional heat resistance on the head of the valve • Liquid nitriding strengthens the entire valve material - not just the surface area • Better ductility beneath the extremely hard magnetite outer layer makes the valve less likely to break, even if contacted by a piston • Greater surface hardness reduces crack formation • Smoother, stronger surface means less valve and valve guide wear than chrome • Resists corrosion and deposits caused by exotic fuels Our diesel performance valves are designed to perform reliably in the extreme conditions that exist in highly boosted turbo diesel engines. Bi-metallic exhaust valves are made from inconel and HNV-3 alloys and are stellite faced to operate under extreme heat conditions. Intake valves are made from 21-4N alloy steel. Both intake and exhaust valves are put through our proprietary five step liquid nitriding process, resulting in valves that are smoother, stronger and more corrosion resistant than traditional chrome plated stainless valves.
